WGU C810 FOUNDATIONS IN HEALTHCARE
DATA MANAGEMENT — 350 PRACTICE
EXAM QUESTIONS
Domain 1: Healthcare Data Fundamentals (Questions 1–100)
Question 1
Which of the following best defines a primary data source in health
information management?
A) A disease registry used for epidemiologic research
B) The Electronic Health Record containing direct patient clinical data
C) An aggregated claims database for billing analysis
D) A hospital's financial ledger
Correct Answer: B
Rationale: Primary data sources are original records that capture patient care
directly, such as the EHR. Registries and aggregated data are secondary
sources.
Question 2
,According to documentation timelines, the History and Physical (H&P) must
be completed within:
A) 8 hours of admission
B) 12 hours of admission
C) 24 hours of admission
D) 48 hours of admission
Correct Answer: C
Rationale: Regulatory standards require the H&P to be documented within 24
hours of the patient's admission.
Question 3
Which method of authentication is considered the most secure for electronic
health records?
A) Handwritten signature on a printed screen capture
B) Username and password only
C) Digital signature combined with a hardware token
D) Voice recognition without a password
Correct Answer: C
Rationale: A digital signature plus a hardware token provides twofactor
authentication, meeting higher security standards.
,Question 4
When correcting an error in a paper health record, the proper technique is to:
A) Erase the mistake and rewrite the entry
B) Use whiteout to hide the error
C) Draw a single line through the error and add the correction with initials
and date
D) Scribble over the error and write the new entry in the margin
Correct Answer: C
Rationale: The audit trail must be preserved; a single linethrough with
correction, dated and initialed, meets compliance.
Question 5
In an electronic health record, an addendum is used to:
A) Delete a previous entry that contains inaccurate information
B) Append new information while preserving the original entry
C) Replace a prior diagnosis with a new one
D) Archive old medication lists
Correct Answer: B
Rationale: An addendum adds information without removing the original,
maintaining the audit trail.
, Question 6
The data element "Blood type: O positive" is most relevant for which purpose?
A) Billing claim submission
B) Determining appropriate blood transfusion
C) Scheduling a followup appointment
D) Calculating length of stay
Correct Answer: B
Rationale: Relevancy means the data is useful for the specific clinical
purpose—in this case, transfusion.
Question 7
Which of the following is a series of successive stages and has beginning and
end points?
A) Data Architecture
B) Data Life Cycle
C) Data Policy
D) Data Governance
Correct Answer: B
Rationale: The data life cycle refers to the series of successive stages that data
passes through, from creation to disposal.
